DESC: The JB Model SH-4 is one of Duncan's - and the world's - most popular pickups and provides the classic sound of a hot-rodded humbucker.Boasting plenty of output without sacrificing tone and adding the right amount of harmonics, sustain, and distortion, the JB Model SH-4 is great for anything from heavy blues to heavy metal - with an emphasis on heavy! But excelling at aggressive music isn't all the SH-4 can do, as it cleans up nicely providing warm, sweet tones. The JB Model SH-4 is built for great tone!
